To all whom it may concemq Be it known that I, HALDoR A. ANDERSON, acitizen of the United; States, residing at Ortley, in the county ofRoberts and State of South Dakota, have invented certain new and useful-Improvei'nents in Photographic- Print-ing Machines; and I do herebydeclare the following to be a full, clear, and exact description-of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention has for its object :to provide an improved photographicprinting machine, and to this end, it consists of the novel devices andcombinations of devices, hereinafter described and defined in theclaims. Y

The invention :isillustrated in the accompanying drawings, wherein likecharacters parts throughout the several views.

As introductory to .the detail description which will follow, thefollowing remarks are thought to be pertinent: In this improved machine,as preferably constructed, photographc prints may be rapidly made eitheron a long ribbon or on individual cards or paper sections. When theprints are made on a ribbon, the ribbon is automatically fedintermittently any desired distance, by movements of the so calledplaten and its actuating slide, so that the photographic print may berepeated over and over again on the same paper or strip. Of course, bychangin the negative, any desired number of ditlerent prints may also bemade on the said ribbon, and the said ribbon may be either of paper orany other properly sensitized or properly. prepared paper. hen thephotographic prints are made on separate cards, these cards will bepresented to the negative by a movement of the platen against thenegative, and when the platen is retracted, the printed cards will bedropped from the platen and preferably into a suitable receptacleprovided therefor.

The preferred construction of the machine is substantially ashereinafter described in detail, and illustrated in the drawings.

"The frame work 1 of the machine is prefera-lily of rectangularconstruction, being provided on top with a face plate '2, and

having at its rear end an upwardly extended back plate 3 which serves asa support for various devices hereinafter described.

So far as the broad idea of my invention is concerned, the negative rmaybe either a at their free ends with pivoted negative clamping bars 7preferably provided with rubber covered edges 8. The lower arm 6 ispivoted to a thin plate 9, to which the glass pane t is detachablysecured by strips 10. The said plate is adapted to be detachably securedin a. recess 11 of the back plate 3 with the plate 4 and negative Zexposed in a rectangular opening 12 formed in said back plate 3. lhcupper arm 5 is pivotally connected to a head 13, which as shown, isadjustably secured on a vertical guide rod 14: attached at its ends tothe said plate 5), as shown in Fig. 15. The coiled spring 15, yieldinglyconnects and tends to draw together the arms 5 and 6. A stop screw 16Works through a hearing 17 of the plate 9, and adjustably, butpositively, limits the downward movement of the lower arm 6, and hencedetermines the elevation of the negative in respect to the opening 12.The opening 12, the glass plate 4, and the negative Z, it will be noted,are located above the face plate 2 or the frame 1. The platen 18, at itslower end, is connected by hinges 19 to an actuating slide 20 that ismounted to slideon top of the face plateZtowar-d and from the back plateand being as shown, held and guided for such movement by flanged guidestrips 21 applied to the opposite edges of the said face pla e A coileespring 22 tends to turn the pi on back or downward on the slide 20, asown in 5 When the slide 20 is move 3 rearward or toward the back plate 3to ,vtreme position, the platen 18 is forces gainst the negative plateby means a lever 23 intermediately pivoted slide 20, and having asshown, its upper end that works on b n 25 secured to the back or? .7 endof lever 23 is connec 26, as shown, by and a short coile 5. ac'

nnecte i 3S variably ilifil" secured on the face plate 2, and as shown,arranged to work over a relatively fixed graduated scale As willhereinafter appear, the position of the stop 31 determines the amount offeed movement that will be given to the sensitized paper ribbon underreturn movement of the actuating slide 20.

, Preferably, the slide 20 is mounted to move on smallrollers 33interposed between recessed portions thereof and the upper sur face orthe face plate The anchoring bracket 26 is made adjustable to set thelever 23 and platen 18 to properly hold either thick card or thin paperbetween the platen and the negative plate, and the spring 28 insures theproper pressure and guards against extreme pressure on the negativeplate. The means for holding these cards on the face of the platen,

while it is being presented to the negative and for dropping the samefrom the platen after the print has been made, may take various forms,but in Figs. 4:, 5, 7 and 8, it is shown as allorded by so called gagepins ZE-l mounted for endwise movements in the lower portion of theplaten 18. The heads of these gage pins are subject to the free ends oilea-f springs 35, the other ends of which springs are secured to the topof the slide 20. The ends of the said spring 35 are so curved, that whenthe platen is turned downward or retracted from'the negative plate, asshown in Fig. 8, said springs will cause the ends of said pins toproject and afford supports for the lower edge of the card Y, see Figs.5 and 8. Preferably, the gage pins 3i are provided with rubber tips andthe platen 18 is covered with a cloth facing. ll hen the platen with theapplied card Y is turned against the negative plate, the pins 3% arepressed backward as shown in Fig. i, and the curved end of the springsthen press the heads of the said pins at such angle that friction willbe suliicient to hold the pins in their retracted positions until theplaten is again turned nearly backward to the position shown in Figs. 5and 8. Hence, under initial movement or the platen away r'ro-nr thenegative plate after the print has been made on a card, the said printedcard will be free to fall om the platen through a suitable passa e inthe rear end portion of the face i onto an clined chute 36, l y which l1 shown,

it will be directed a 2 ll mounted ew Alald mecln frame 1,below the faceplate2 and above the drawer37. These drawers 38 while desirable, are notnecessary and form no part of this invention.

The slide 20 spring retracted orinoved away from the negative plate andpreferably, this is accomplished by a quite heavy coiled spring 39attached atone end to the bottom of the face plate 2, and at its otherend to a perforated strap 40, that runs over a pin wheel or hub 41carried by a small vertical shaft 42, mounted in suitable bearings onthe lower portion of the back plate 8. The other end of this strap 40 isattached to one side of a slide 20. For the construction just described,see Figs. 2, 3 and 17. The spring 39 is, ofcourse, more than strongenough to overcome the spring 22.

For a purpose which will presently appear, the so called pin wheel orhub 41 is formed with ratchet teeth 43 on its upper edge so that itconstitutes one member of a clutch device shown in Fig. 16.

To reinforce or augment the action of the spring 89, a,secondary springdevice is employed. As preferably constructed, this secondary springdevice comprises a bell crank lever 44 which is pivoted to a bearing 45shown as secured to a horizontal partition 1 of a frame 1. Therelatively short lower arm of this bell crank 44 is subject to a leafspring 46, secured at one end to the said partition 1*, and having atits free end a seat 47. The relatively long upper end of said bell cranklever 44 is shown as provided with a roller that works bctweenrelatively long and short bearings 48 and 49 secured to the bottom ofthe slide 20, and depending freely through an elongatedslot in the faceplate 2. The operation of this device is as follows: \Vhen theparts arein the position shown in Fig. 3, the roller equipped upper end of thebell crank is pressed against the short, bearing 49 under the action ofthe spring 46 on the lower arm of said bell crank; and hence, at thistime, the spring 46 cocperates with the spring 39 to insure sutiicientforce to cause the platen 18 to tightly press the card Y against thenegative plate. When the slide 20 is drawn outward or retractedapproximately to an intermediate position, the end of the lower arm ofthe bell crank 44 passes into the seat 47 of the spring 46,. and theroller atthe end of the upper arm of said bell c ank passes under theshortbearing 49, so hat the said slide 20 may befreely moved onward toits extreme outermost or ret-ractefd position. When the slide 20 ismoved forward, the long bearing 48 engages the roller at the upper endof the bell crank and'forces' the same upward between the said twobearings 48 and 49, and positively forces the lower arm of said bellcrank out of the seat supported by a bracket 51 secured to the backplate 3 above the opening 12 thereof. At its front end, this holder isshown as provided with an inclined end plate 52, and is also shown asprovided with an inclined follower plate 53 having a projectingoperative bail 54. \Vhen the hinged end plate 52 is forced upward, andthe follower is forced, forward, a stack of cards contained in theholder may be shifted so that their ends project successively in thesame direction, thereby facilitating the picking up of the cards.

The paper ribbon Y upon which the prints may be successively taken, isprimarily rolled and preferably contained within a holding-drum 55, seeFigs. 1, 2, 3 and 13, which holder is provided with a hinged sidesection 56. 5 The dr p 11 55 is rigidly secured to a rectangularsupporting frame 57 that is mounted to slide verticallyupon the backplate 3. The free edge of the hinged section 56 is shown as providedwith projections 56 adapted to be sprung into.

notches 58 of upper and lower flanges 59. As shown in Fig. 14, the frame57 has vertical retaining strips 60 that are adapted to slide upona-thin sheet metal plate 61, which in turn, is directly secured on theback plate 3. As shown, the-drum 55 is applied to the left hand end ofthe vertically adjustable supporting frame 57. To the right hand end ofthe said supporting frame 57, a ribbon winding or rolling mechanism isapplied. This winding -mechanism, as shown, comprises as follows: Thismechanism is best shown in F igs. 1, 11, 12 and.16. On open endedreceiving cylinder or drum 62 is rigidly secured in an upright positionto the.

right hand end of the vertically adjustable bearing frame 57, by meansof brackets 63, see Figs. 11. and 16. At its left hand side thereceiving drum 62 has a lateral entrance passage 64 for the paper ribbonor strip Y An approximately conical drum bottom v65 is located belowthe. drum 62, and is rotatively mounted in a bearing plate 66 rigidlysecured to the frame57. The spur gear 67 is secured-to the rotary bottom65, and an upwardly extended shaft 68 is secured at its lower end to thesaid rotary bottom 65, and projects upward axially through the receivingdrum 62. A coiled spring blade 69 is secured at the .inner edge to theshaft 68. The outer edge "of this spring blade 69 is spring pressedagainsb the very smooth inner surface of the receiving drum 62, and

aim.

to give the same greater frictional contact I 57 and the ribbonactuating devices which with the paper ribbon Y than there is be tweenthe said paper ribbon and the smooth inner surface of the drum G2, athin sheet of rubber cloth or other material is preferably secured tothe said spring blade 69, as shown in Fig. 11. The gear 67 meshes with agear 71 secured on the lower end of a vertically disposed teed roller72, the shaft of which is mounted in suitable bearings 73 on the bearingframe 57. A small idle ribbon pressing roller 74 is movably mounted inthe bearings 73, and is shown as spring pressedagainst the feed roller72 by leat' springs 75, secured at one end to the frame The gear 71meshes with an intermediate gear 76 mounted in suitable bearings 77secured on the lower portion of the frame 54. The intermediate gear 76meshes with a driving gear 78, which as shown, is connected by acontracted neck 7 9 to a sleeve 80, that is telescoped into the lowerend of a feed roller 81, and is rigidly secured to said roller. At itsupper end, this roller-8l is provided with a headed trunnion 82journaled in a 4 bearing bracket 83 secured to the upper portion of theframe 57. The roller 81 is there- :tore, capable of swinging movementsat its lower end, but is normally held against such swinging movement bya forked bearing 8 1- and coiiperating spring 85, the former of whichembraces the neck 79 of the roller sleeve 80, and the free end of whichspring engages an annular shoulder of the gear 78 and yieldingly holdsthe roller 80 against outward swinging movements, See Figs. 12 and 16. Asmall idle pressure roller 86 cooperates with the roller 81 and isspring pressed toward the sameby leaf springs 8? applied to the upperand lower portions of the frame 57. The roller 86 is provided at itsends with trunnions that work in slots of the upper and lower bearings83 and 8st respectively, and the springs 87 directly engage saidtrunnions, see l igs. l2 and 16. A plunger 88 is mounted for axialmovements through the gear T8 and its neck ?9 and is connectedto rotatewith the roller 81, as shown by a cross pin 89 secured to the upper endof said plunger and seated in vertical slots of the roller sleeve 80. Acoiled spring JO yieldingly presses the plunger 88 downward. iiiigidlysecured to the plunger 88, below i -'ear T8, is a half clutch 91 thatengage the half clutch d3 of the also, the plunger 88, below is formedwith a conical i to engage the conical pin the ha point tl ollers and 86may covered.

printed, the

are carried thereby, are moved upward on the back plate 3 to theinoperative position shown in Fig. 3, and in this position, the ribbonand its actuating mechanism is preterably contained within a dark box 92which is provided with a hinged drop bottom 93. in practice, the cardbox 50 will be offset to one side of the machine so that it does notinterfere with vertical movements of the frame 57. When the prints areto be taken on the ribbon, the frame 57 is lowered and the ribbonactuating mechanism is positioned as best shown in Figs; 1 and in thislowered position, the ribbon Y will be -fed between the negative plate Zand the platen 18 and by the platen will be pressed against the negativeplate, when the slide 20 is moved to its extreme position toward saidnegative plate. Also at such time, the feed roller 81 is directlyconnected to the shaft 12 by the engaged clutch members 48 and 4-1, andthe feed roller 7'2 is indirectly connected thereto through the ears 71,?6 and 78, so that each time the slide 20 is moved outward to contractthe platen, a step 01'? movement will be imparted to the paper ribbon YThe extent of movement thus given to the ribbon will depend on theamount of outward movement given to the slide 20, and through the strap4-0 to the pin wheel 41. As already stated, the outward movement of thesaid slide 20 will be variably limited by the adjustable stop 31. Thegradnations on the scale 32 indicate the position of the stop 31 fordifferent width photos, such as quarter cabinet, half cabinet threequarter cabinet and cabinet. Obviously, the winding shaft 68 and itsblade 69 are rotated simultaneously with rotation of E e feed rollers 72and 81. The spring blade 69 will press the inner end of the ribbon Yagainst the inner surface of the drum 62 and cause the same to be woundinto a coil. The coiled paper or ribbon will drop into the conicalrotary bottom and the latter by its rotary movement, will assist inkeeping the paper coiled. "When the ribbon has been printed anddelivered into the drum 62, it may be readily lifted out of the upperend thereof. The purpose of conner the roller 81 for swinging movementsthe roller is to permit the paper when to be engaged and started on itstrav l en. the said twc lers. At any time, may be cut or the rollers '7the pm matic marking device, as shown in Figs. 1',

as shown in the form of a screw closed split sleeve 96, adapted to holda short pencil 97.

A spring 98 applied to the arm 94 and bear-- ing 95 yieldingly holdssaid arm 94 against a stop 99 on one end of the platen,and with thepoint of the pencil projecting beyond the face of the platen, as .bestshown in Fig. 22, so that when the platen is forced against the ribbon,the point of the pencil will be moved downward on the ribbon and make amark on the back thereof.

' The light controlling curtain 100, see Fig.

3, is mounted on an automatically spring wound roller 101 of the windowshade type, which is supported by the back plate 3 just above the llghtopening 12. To the lower edge of this curtain 100, the upper ends of apair of cords 102 are attached. These cords extend downward under guidesheaves 103 mounted in openings in the lower portion of the back plate3, thence upward over similar guide sheaves 104 mounted in the same wayin said plate 3, and located very slightly below the face plate 2.' Fromthe .sheaves 104, the cords 102 exten below the face plate 2 and areattached to depending ams 105, see Figs. 3 and 6 of a sup lemental slide106 mounted to slide on top 0 the main slide 20 and also held by theflanged guide strips 21. The arms 105 are afforded by the downturnedends of an operating bail or hand piece 107, which is secured to the topof the said supplemental slide 106. A coiled tension spring 108 connectsthe supplemental slide 106 to the rear portion of the main slide 20,being as shown, attached at. its other end to a stop bracket 109 securedto the outer edge of said main slide 20. This stop 109' limits theoutward movement of the supplemental slide on the main slide, and thesaid spring tends to hold said supplemental slide engaged with the saidstop.

The hand piece 107 on the supplemental slide 106 affords the primarymeans for actuating the platen, the light curtain and the ribbon feedingmechanism. Normally the spring 39 holds the platen in its operativeposition against the negative plate as already described. Normally alsothe spring 108 will hold the supplemental slide 106 against the stopbracket 109 'of the main slide 20, in which position the lightcontrolling curtain 100 will be drawn downward over the light, passage12. The curtain 100 is raised as shown in Fig. 3 by forcingthesupplemental slide 106 into its extreme position shownin said Fig. 3,againstthe tension of-the spring 108. Hence, it is necessary topositively hold the supplemental slide 106 in itsinnerdog 119 pivoted tosaid case 1.

most position shown in Fig. 3, long enough to permit the taking of theprint, which will, however usually be but a few seconds. When the printis taken, if the supplemental slide be released, the spring 108 willforce the same outward against the stop bracket 109, thereby drawing thecurtain 100 into its closed position while the platen is still heldagainst the negative plate. To move the platen from the negative .plate,the supplemental slide 106, which engaged with the bracket 109, is drawnfarther outward, thereby carrying with it the main slide and forcing theplaten into its retracted position shown in Fig. 5. The spring 108should be of greater tension than the spring 39, so that under inwardmovements of the two slides,

A vignette curtain 110 located outward of the light controlling curtain100, is connected at its upper end to a spring acting roller 111 mountedon the upper portion of the back plate 3. This curtain 111 at its loweredge, has depending strap portions 112 that are secured to a roller 113mounted in bearings on the lower portion of the back plate 3, andprovided at one end with a sheave 114 to which a cord 115 is attached,the other end of said cord being extended forward and attached to a drum116 mounted on one side of the lower front portion of the case or frame1, see Figs. 3, 10, 18, 19 and 20. The drum 116 is provided with anoperating crank 117 and with a ratchet wheel 118, which latter isadapted to be engaged and held by a lock As is evident. the pawl andratchet device 118119 seri e to hold the curtain 110 with any one of itsseveral light passages alined with the light passage 12, and the backplate 3. The.

curtain 110 is preferably made of the customary 'material. trollingcurtain 100 is preferably made of asuitabletranslucent'cloth or materialcolored yellow or some -other.color,, which will ob- 'struct' light'rayssuch as required to print the negative. Thiscurtain from a broadpoint-of view, performsth'e function of a shutter, but is preferablymade translucent so that the operator may see to properly set thenegative from the dark. room. 1

In practice, I apply a register or counter which is autonr'iaticalhoperated by movemonts of the platen toward and from an The so calledlight con-' i operative position to indicate the number of printssuccessively taken from the same negative.
